PTO speeds 3pt.hitch pic

There is the flat belt drive on the side and a spline shaft coming out the back. If the engine speed is 1500 rpm, what is the rpms of the flat belt drive? Rpms of the Spline drive?

I think the mower needs about 3200 Rpm, does that sound right? It has 3 each of 21 inch blades. You can see the belt and spline in the picture where I am building a 3 pt hitch.

Here is what mine looked like, built these 3 years ago.I have since sold tractor. Last time I seen My C it was sitting on a dealers show room floor.

PTO wheels?? The PTO assembly ratios are the same for both the B and C. The splined PTO shaft runs at 40% of engine speed and the belt pulley shaft runs at 75% of engine speed. If you also want the engine-to-ground speed ratio, you'll need the tooth counts for the transmission gears, the differential and the final drive, along with the rolling radius of your rear tires. The tooth counts for the appropriate gears are listed in the B/C parts book. The transmission and differential ratios are the same for both the B and C. The final drive ratios are different plus the C has different ratios, depending on tractor serial number. Again, the parts book would permit calculating such ratios. That's interesting information and some time when I get a chance, I may work up those numbers and post them on my B web site.
